Generally, we have a healthy skepticism towards alternative medicine. Most of the things tried over the years (vitamin C, echinacea, etc.) turned out to have dubious evidence behind them upon exploaration. With pancreatitis, most reputable sites are careful to refer you to a doctor before recommending anything other than conventional medicine. This is especially true for acute pancreatitis, which in extreme cases can be fatal if not treated.
Here are some resources that do a good job of explaining the alternative therapies under consideration (while careful not to endorse them):
The University of Maryland Medical Center’s Complementary and Alternative Medicine Guide, pancreatitis section — discusses the role of antioxidant levels in the blood, as well as nutritional tips and potentially helpful supplements.
Dr. Weil on Pancreatitis — with a focus on anti-inflammatory herbs, and Chinese medicine.
National Pancreas Foundation on Complementary Therapies for Chronic Pancreatitis — recommends massage, meditation, exercise and laughter. (“Can’t hurt!”)
A study on the use of yoga for rehabiliation of chronic pancreatitis — 62% reduction in self-reported pain levels after a 12 week yoga program.
